Move the method description
Move the method description to the right hand side of the list of methods. This allows us to extend the list of methods so that the info doesn't fall of the terminal on a 80x24 system that is using the frame buffer such as shredos. Also updated the information, making it more description in terms of describing the passes used for each method.
